Method for installing ultra-deep section type large-diameter working well pressure sinking system
The invention discloses a mounting method of an ultra-deep section type large-diameter working well pressure sinking system, and relates to the technical field of working well construction. The method comprises the following steps: step 1, reinforcing a soil body; secondly, an open caisson foundation pit is excavated; thirdly, a ballasting body foundation pit is excavated; fourthly, a ballasting body is constructed in the ballasting body foundation pit; 5, mounting a counter-force frame; step 6, pressurizing and sinking; seventhly, the counter-force frame is dismantled; and eighthly, the ballasting body is dismantled. Controllable thrust is provided for the well body of the open caisson, so that the open caisson sinks faster and more controllably, meanwhile, the open caisson can be manufactured in small sections, and the open caisson has more advantages in safety risk control; ballast weight is provided for the counter-force device through the well periphery balance weight platform, the hoop effect on the open caisson is achieved, the ground anchor steel pipe and the prefabricated and cast-in-place combined concrete structure balance weight are adopted as the well periphery balance weight platform, the construction technology is simple and convenient, and the construction quality is easier to control.
本发明公开了一种超深节段式大直径工作井压沉系统安装方法，涉及工作井施工技术领域；本发明包括如下步骤：步骤一、土体加固；步骤二、开挖沉井基坑；步骤三、开挖压重体基坑；步骤四、在压重体基坑内施工压重体；步骤五、安装反力架；步骤六、加压下沉；步骤七、拆除反力架；步骤八、拆除压重体。本发明通过向沉井井体提供可控推力，使沉井下沉更快、更可控，同时沉井可小节段制作，在安全风险控制上更具优势；通过井周配重平台为反力装置提供压载重量，并对沉井起“抱箍”作用，采用地锚钢管+预制与现浇组合混凝土结构配重作为井周配重平台，施工工艺简便，施工质量更易控制。
